“…In the setting of HF, the OER M represents tissue oxygen consumption in peripheral tissue that is subject to the vasoconstriction, endothelial dysfunction, diminished cardiac output and fluid overload. 15 The directly measured StO2 value itself has been investigated in the outpatient HF population 16 and in the acutely decompensated ED population 17 with promising results. The advantage of OER M measurement is the ability to take into account arterial blood oxygen content entering the tissue, important as hypoxemia often results from severe HF.…”

The authors evaluated peripheral tissue oxygenation during treatment of acutely decompensated congestive heart failure (CHF) to determine whether differences exist between patients who experienced adverse outcomes (AO), defined as death or readmission within 6 months, and patients who did not (non-AO). This prospective, observational study measured differential absorption spectroscopy-derived tissue hemoglobin oxygenation (S(t) O(2) ) in CHF patients from presentation through hospital discharge to determine whether differences between the AO and non-AO groups exist. Of 52 patients, 6 died and 27 were readmitted. In the non-AO group, S(t) O(2) increased from admission to discharge by 5.2% ( P<.01; 95% confidence interval, 1.7%-8.7%). No S(t) O(2) change occurred in the AO group (2.3%; P=.42; 95% CI, -2.2%-6.8%). Tissue oxygenation increased during inpatient treatment in CHF patients without future adverse outcomes, but was unchanged for those who later died or were readmitted. Lack of improvement may be associated with higher rates of death and readmission.
